Assembly of Tailored Thiophene Oligomers on Gold Electrodes - Film Formation and Properties

  • Published:
MRS Online Proceedings Library Aims and scope

Abstract

To examine the potential to apply chemically modified surfaces in organic thin film transistors (TFT), we report the synthesis and characterization of two tailored series of oligothiophene compounds. The oligomers have thiol end groups for coupling to gold electrodes and have regio-regular alkyl substitutions corresponding to Head-Head (HH-) and Head-Tail (HT-) molecular conformations. Variations in chain length, structures and end groups have enabled a detailed study of the deposition of films from solution and the films’ properties.
